The embodiment discloses a perforated tab battery, referring to fig. 1, which comprises a first substrate 1 and a second substrate 2, wherein a collector electrode 3 is arranged between the first substrate 1 and the second substrate 2, the collector electrode 3 comprises a collector tab 301, and the collector tab 301 is exposed through a window area 101 arranged on the first substrate 1 to form a perforated tab structure; the collector tab 301 is provided with a printed insulating layer 4, and the printed insulating layer 4 is used for supporting and fixing the collector tab 301, wherein the printed insulating layer 4 can be formed by curing printing insulating oil through UV light or oxidation.

In this embodiment, the printed insulating layer 4 is disposed on the collector tab 301, and the collector tab 301 is supported and fixed by using the cured printed insulating layer 4, so that the collector tab 301 does not need to rely on the second substrate 2 to be supported and fixed, that is, the side, away from the window area 101, of the collector tab 301 does not need to be provided with the second substrate 2, thereby improving the setting flexibility of the second substrate 2.

Further, the collector tab 301 is further provided with a first adhesive layer 5, and the first adhesive layer 5 is used for adhering the collector tab 301 to an electrical appliance (not shown in the drawing). The collector tab is adhered to the electric appliance by the adhesion effect of the first adhesive layer, so that the electric connection between the collector tab and the electric appliance is ensured.

Specifically, the collector electrode 3 includes a first collector electrode and a second collector electrode, a battery component 6 is further disposed between the first substrate 1 and the second substrate 2, and the battery component 6 is encapsulated by a second adhesive layer 7; the positive and negative electrodes of the battery member 6 are connected to the first collector electrode and the second collector electrode, respectively. The battery part 6 comprises a first electrode, an electrolyte membrane layer and a second electrode, and the first collector, the first electrode, the electrolyte membrane layer, the second electrode and the second collector are sequentially and electrically connected to form a complete flexible battery structure. The first adhesive layer 5 and the second adhesive layer 7 are made of the same material, and can be synchronously arranged in the processing process, so that the processing flow is simplified and the efficiency is improved.

As a preferable solution of the above embodiment, as shown in fig. a and b in fig. 2, a glue passing gap 8 is provided between the collector tab 301 and the window area 101, and the printed insulating layer 4 and/or the first glue layer 5 are partially disposed in the glue passing gap 8. In this way, as one of the arrangement modes of the printed insulating layer 4/the first adhesive layer 5 and the collector tab 301, the cured printed insulating layer 4 is arranged in the adhesive passing gap 8 to enhance the external edge strength of the collector tab 301, and the first adhesive layer 5 is arranged in the adhesive passing gap 8 to bond the edge of the collector tab 301 and the electric appliance.

Alternatively, as shown in fig. d and f of fig. 2, the collector tab 301 is provided with a through-adhesive hole 9 therethrough, and the printed insulating layer 4 and/or the first adhesive layer 5 are partially disposed in the through-adhesive hole 9. In this way, as one of the setting modes of the printed insulating layer 4/the first adhesive layer 5 and the collector tab 301, the setting of the cured printed insulating layer 4 in the adhesive through hole 9 can enhance the middle strength of the collector tab 301, and the setting of the first adhesive layer 5 in the adhesive through gap 8 can bond the middle of the collector tab 301 and the electric appliance with each other.

Alternatively, as shown in fig. 2 c and e, the printed insulating layer 4 and/or the first glue layer 5 are arranged in both the glue holes 9 and the glue gaps 8. In this way, as one of the arrangement modes of the printed insulating layer 4/the first adhesive layer 5 and the collector tab 301, the through adhesive hole 9 and the through adhesive gap 8 are simultaneously arranged on the collector tab 301, and the printed insulating layer 4/the first adhesive layer 5 is simultaneously arranged in the through adhesive hole 9 and the through adhesive gap 8. It can be appreciated that the above meaning may be understood that the printed insulating layer 4 is disposed in the through glue hole 9 and the first glue layer 5 is disposed in the through glue gap 8, or the printed insulating layer 4 is disposed in the through glue gap 8 and the first glue layer 5 is disposed in the through glue hole 9, or the printed insulating layer 4 is disposed in the through glue hole 9 and the through glue gap 8 and the first glue layer 5 is disposed in the through glue gap 8, etc., which are not listed one by one, and those skilled in the art can avoid other disposing modes that are conceivable without performing creative labor through the above technical scheme, and should also belong to the protection scope of the present application.

Optionally, the first adhesive layer 5 penetrates through the collector tab 301 through the adhesive through hole 9, or the edge of the first adhesive layer 5 is larger than the collector tab 301, i.e. the first adhesive layer 5 is disposed in the adhesive through gap 8 between the collector tab 301 and the window region 101. By the arrangement, the first adhesive layer 5 is arranged at the edge and the middle of the collector tab 301, so that the bonding firmness between the collector tab 301 and the electric appliance is improved.

As a preferred embodiment of the above embodiment, as shown in fig. 3, the first adhesive layer 5 is coated on the outer side of the printed insulating layer 4. So arranged, the solidified printed insulating layer 4 is utilized to provide supporting and fixing functions for the collector tab 301; and then the first adhesive layer 5 is wrapped on the outer side of the printed insulating layer 4 so as to jointly adhere the collector tab 301 and the printed insulating layer 4 to the electric appliance.

Alternatively, as shown in fig. 4, the printed insulating layer 4 is coated on the outer side of the first adhesive layer 5. So arranged, the collector tab 301 is adhered and fixed on the electric appliance by the first adhesive layer 5; the printed insulating layer 4 is wrapped on the outer side of the first adhesive layer 5, so that the fixed printed insulating layer 4 can provide supporting and fixing functions for the collector tab 301 and the first adhesive layer 5.

The two above-mentioned arrangements of the first adhesive layer 5 and the printed insulating layer 4 can be freely selected by those skilled in the art according to the actual situation of the site, and the present application is not limited thereto.

As a preferred version of the above embodiment, as shown in fig. 4, the area of the second substrate 2 is smaller than the area of the first substrate 1. So arranged, since the collector tab 301 is supported and fixed by the printed insulating layer 4 in the present application, the second substrate 2 is not required to be relied on for supporting and fixing; based on the above, the present embodiment can remove the portion of the second substrate 2 aligned with the collector tab 301, so that the area of the second substrate 2 of the final flexible battery is smaller than that of the first substrate 1, thereby improving the flexibility of the arrangement of the second substrate 2.

Specifically, as shown in fig. 5, the printed insulating layer 4 is at least partially connected to the first substrate 1. In this way, the portion of the second substrate 2 aligned with the collector tab 301 is removed, so that the printed insulating layer 4 cannot be used as a connection fixing point by connecting with the second substrate 2, or only a small portion of the printed insulating layer 4 is connected with the second substrate 2 to be used as a connection fixing point, which can result in that the fixing point of the printed insulating layer 4 cannot bear enough deformation force, and deformation and fracture are easily caused by mutual extrusion and adhesion of the collector tab 301 and the electrical appliance in the practical application process. Based on the above considerations, this embodiment requires that at least part of the printed insulating layer 4 is connected to the first substrate 1, and uses the first substrate 1 as a connection fixing point of the printed insulating layer 4, so as to ensure that the printed insulating layer 4 can withstand a sufficient deformation force, and ensure that the collector tab 301 is not easily deformed during practical application.

The above arrangement of the printed insulating layer 4/the first adhesive layer 5 and the collector tab 301 can be specifically referred to fig. 5. It should be understood that fig. 5 is only an example of a part of the arrangement, and those skilled in the art, after understanding the technical solutions of the present application, may conceive other arrangements without creative effort from the accompanying drawings, and shall also fall within the protection scope of the present application.

It should be noted that, other contents of the perforated tab battery disclosed in the present utility model are related art, and are not described herein.

The foregoing is merely an alternative embodiment of the present utility model, and is not intended to limit the scope of the present utility model, and all applications of the present utility model directly/indirectly in other related technical fields are included in the scope of the present utility model.
